Can't use OpenSSH to open a session

Can't use OpenSSH to open a session

I followed (sort of) the post about integration of OpenSSH in WinSCP.
First, it looks like %WINDIR%\Sysnative doesn't exists anymore, bash.exe is now located in %WINDIR%\System32.
Then, calling %WINDIR%\System32\bash.exe doesn't work since WinSCP can't find the executable (which is in this directory).
I tried several workarounds (using .bat file for example) but, still, finally WinSCP can't find the EXEs needed to run OpenSSH.
